PiffPassPoff

With the advent of password wallet apps, and the great keychain function that comes with iOS and MacOS there's no need to be making up insecure passwords (or even worse - reusing them on all your accounts!). 

This simple little app allows you to have some control over what type of password you want: length, types of characters used and types of characters not used are all configurable. It's as easy as select a few toggles, generate the password, then copy to your clipboard, after that simply paste into the password field you're using.
